Hydraulic presses use a hydraulic cylinder to generate large mechanical forces. Utilizing Pascal’s law, in which pressure applied to a confined fluid occurs throughout the fluid, hydraulic presses apply a moderate mechanical force to a small cross-sectional area, which is transferred to a larger cross-sectional area in the hydraulic cylinder. This allows for the hydraulic cylinder to generate a greater pressure to the application than what was applied.

Hydraulic presses are used in many manufacturing operations and take up less space than mechanical presses. Commonly, they are...
